What is modified atmosphere storage?

Modified atmosphere storage, also known as modified atmosphere preservation, is to achieve the purpose of storage and preservation by controlling the proportion of gases. At present, there are two main ways widely used in China. One is controlled atmosphere cold storage, that is, artificially controlling the gas in the storage environment of controlled atmosphere cold storage to realize fruit preservation. Controlled atmosphere refrigeration needs to accurately control the concentration of gas components required by different fruits and strictly control the temperature and humidity. Combined with low temperature controlled atmosphere, the fresh-keeping effect (color, hardness, etc. ) is superior to ordinary refrigeration, and the preservation period is obviously prolonged.

The other is plastic film bag modified atmosphere preservation, also known as modified atmosphere preservation packaging, that is, according to the physiological characteristics of food and the needs of preservation, food is stored in a suitable proportion of packaging to extend its preservation period. Widely used in the preservation of fresh fruits and vegetables, with an annual growth rate of 20%. The effect of the combination of fresh-keeping packaging and refrigeration is basically close to that of modified atmosphere refrigeration.
